Why Selection Is Changing Direction

Climate change has affected us in many ways, but it was even more influential on organisms and their community. The Earth is gradually heating and we are left to deal with the consequences. Homes are being destroyed, organisms are dying, and resources are running low. Since 1880, Our Earth’s temperature had increased by about 0.8 degrees Celsius. Climate change is affecting the Earth and scientists say that one more degree will greatly affect people from all over the world. There are many consequences of climate change and each one has a great impact on all of us, but organisms’ homes are being destroyed and thousands of species are dying out. These organisms are imperative to our world and how it functions.

In this article the authors present well researched information to prove their point that global warming could lead to a disruption of the connectedness within different populations of animals and could even cause a reorganization of species communities. The authors provide an ample amount of information about what global warming has already done to animals in order to support their predictions of what this means for the future. Despite having more than enough evidence to support that global warming is affecting animals, a majority of the paper is hypotheticals about what could happen for the future thus making it less credible. The authors do an exceptional job of using ethos and pathos throughout the piece. They use ethos when discussing

Due to the immense anthropogenic release of green house carbon emissions into the atmosphere, there has been and will be major detrimental effects on human resources and the ecosystem. For example, by the middle of the 21stcentury, River runoff will increase by 40% in northern latitudes and also in a few tropical areas, while in dry regions it will decrease by 30%. Some of these tropical areas have already reported and are experiencing water droughts that will only get worse (Gillman 2008). In addition, if temperatures continue to increase to 1.8-5.4 degrees, food productivity and resources will be affected. When the temperatures reach the lower latitudes of what is predicted, there will be a slight increase in food productivity for a little while. However, when the temperatures reach the higher end of the latitudes, food productivity will

Scientists have been undergoing studies to determine ways organisms change to adapt to their changing environment. Most research and theories are determining that species are not going to be able to evolve fast enough to undergo the climate changing. This topic is making people wonder, since animals might be having difficulty evolving to their environment fast enough, are humans going to have the same problem. Scientists apply the theory of evolution to the impacts that climate change will have on the diversity and distribution of species by analyzing how quickly the species are adapting to different climates (Stolte, 2013). Scientist are using evolutionary biology to make informed decisions to solve the problem by comparing their rates of evolution to the rates of climate change (Stolte, 2013). Most scientists are studying to determine if species will evolve fast enough to be able to survive as the climate is changing rapidly. Species have been moving to accommodate with the change, as a consequence becoming invasive species. Species need to change to their behaviours as well so they can keep up with the climate change.

Climate change will not only accelerate the species extinction rate, but also bring a higher chances of survival of certain endangered species, which indicates that the impact of climate change on biodiversity is double-sided (Bellard et al. 2012).

Climate change is something that affects our Earth many times in greater ways than we would like to acknowledge. Earth’s temperature has been steadily rising since the beginning of time, but we have seen a huge increase starting in the 20th century, when industrialization began to happen. The issues that arise from climate change are happening more often and at a greater scale. Recently we see the way that climate change affects biodiversity.

Due to climate change both the land and the marine distribution is changing, causing numerous problem for human beings. The direct impact of climate change is on the food availability due to redistribution of species, since the areas that are suitable for crop production will either become too dry or will be under water creating a shortage of food worldwide. Animals are migrating to new areas to increase their survival chance, making it difficult for humans to access the same food that they once had before the migration. Fishes are the best example of species shift, due to climate change, the water temperature is rising causing the fishes to travel deep down into the ocean where it is cooler. As the fish travels further down, harvesting fish will become expensive causing economic crises eventually affecting the human well-being. On the other hand, the changing climate change is also posing new health risks for humans, such as some countries are now suffering from malaria, a disease transmitted by mosquitoes. Due to a rise in worldwide temperature, mosquitoes can travel to numerous suitable places. An indirect effect of climate change will be the stress that the plants are facing now. Because of lack of trees on land, the carbon dioxide rate in the atmosphere is increasing which is raising the temperature and melting the tundra region, thus raising the water level. Because of climate change, humans are encountering various problems that can only be solved if the governments take initiative and find a solution for the situation. If world leaders wait any longer, a major catastrophic situation can occur that will dramatically affect human

If there is no effort done to help stop global warming, more than half of the Earth’s species will go extinct. Climate change poses a threat to to Earth’s essential species, because an increase in temperature will not be suitable for arctic animals

2. Increasing global temperatures are expected to disrupt ecosystems, pushing to extinction those species that cannot adapt.

The role of climate in the origin and adaptations of humans relate to the past and the future. Several hypotheses have been proposed that intimates that climate driven environmental changes were responsible for hominin speciation, the morphological shift to bipedality, enlarged cranial capacity, behavioral adaptability, cultural innovations, and intercontinental immigrations events. These hypotheses are based on correlations between climate shifts documented in oceanic deposits and events in hominin evolution recorded by fossils (Evans, 2012). Therefore, all organisms encounter some environmental change which could affect these organisms by raising the level of instability and uncertainly in their survival conditions, because some organisms prefer a particular type of vegetation or temperature. But, when the organisms’ habitat change, they can move and track their habitat or adapt to the new habitat by genetic change (human origins, 2016). Meanwhile, the link between climate change and biodiversity has been establish. Climate has always changed with ecosystems and species coming and going, rapid climate change effects ecosystems and species ability to adapt and so biodiversity loss increase. But, from a human point, the rapid climate change and accelerations biodiversity loss human security is at risk; such as a major change in the food chain which we depend on, water resources may change, recede, or disappear, and medicines and other resources in which we rely on may be harder to obtain as the plants are derived from what they need to survive reduces or disappear (Shah,

Climate change has been a debatable and concerning topic involving human activities and their long term effects on climate condition across the globe. Climate change are primarily caused by many factors, ra natural or artificial. Natural activities such as volcanic eruption, solar radiations and plate tectonic movements are various influential factors climate change. While these natural events aren’t controllable by humans, it’s also proven that recent human activities have also contributed to climate change. We usually refer to this as global warming. Climate change is an important issue to a concerned citizen because it can affect many animal habitats and the global temperature we will be living in. One of the most commonly known habitat

On planet Earth, many species have evolved to adapt to the environment so they can survive. Some of the species’ evolution was driven by global warming. As an article entitled “Conditions of Life: How Climate Change Has Driven Evolution” stated “They find that there have been six distinct waves of species diversity, and that the driving force of those waves has likely been climate change” (Walsh). Climate change has led to many changed is some biomes. Thus, species that live in that biome would have to adapt and change, or they will die. These changed and evolutions will eventually create a new kind of species that might be adorable or fascinating for scientists to study about. The next time you visit the zoo and you see a new species, there is a possibility that global warming might be the

Globally, most of the species (both flora and fauna) are under serious threat from direct and indirect human activities; while the direct activities such as deforestation leads to species habitat fragmentation and loss, on the other hand modifies climatic conditions coupled with gas emissions. The synergistic impact of these human driven activities questions the survivability of organisms in the morphed climatic environments. At one level fragmented habitats increase intra and inter species competitions, resulting in decline of population of species, grouping them under rare and threatened category. At other level, the amplified global temperatures in parallel with low precipitation rates, not only creates unsuitable external habitat conditions but also impose internal changes in biological clock and physiological processes of the organisms, in additions to their life history traits (Reynold et al. 2003, Price and Gittleman, 2007). This kind of changed scenario both externally and internally, brings incompatibility in the organism to cope with fluctuating climatic conditions, finally making the species as vulnerable and forcing into the process of extinction.

The ecological consequences of global climate change are expected to be drastic although not much is known as to how individual species will react to these changes. Irrespective of the causes of climate change, whether anthropogenic or natural, it is imperative that we address these concerns, as they will have widespread impacts on the human species, both directly and indirectly through forcings on other species. The climate is not expected to shift evenly and the ways in which certain species adapt or migrate due to these changes could be erratic and unpredictable. The rate at which the earth’s climate is currently changing is unprecedented and has not been seen in the past 450,000 years. Although many

Global warming is a serious issue in our world that affects billions of living organisms and has the potential to eradicate sustainable use of our planet’s ecosystems. It therefore poses a grave threat to not only animals, but also humans who rely on resources extracted from our ecosystems for existence. The Kyoto Protocol was the first global greenhouse gas reduction treaty signed by countries across the world. Since every country contributes to the rising number of greenhouse gases into the air, it was crucial to have as many countries as possible be involved in its output reduction. Furthermore, the effects of climate change can have significant negative outcomes on living things as a whole including biodiversity loss, ecosystem degradation and sea level rising (Effects of Global Warming, Bradford). Since many of these negative environmental outcomes also effect humans across the world, it had become essential and in the best interest of every country to find a way to slow the amount of greenhouse gases being released.
