DISCUSS THE CHALLENGES ASSOCIATED WITH BIODIVERSITY LOSS FOR 21ST CENTURY CONSERVATION BIOLOGISTS AND SOCIETY AS A WHOLE
Although sustainable development has been at the forefront of international agenda for many years, we continue to focus on the growth of the economy without worrying about the impact on the environment. Currently, our ecological footprint (the area in hectares that we require to provide us with the ecological goods and services we use) is far exceeding our biocapacity (the actual land available to provide these services); with the human population requiring over 1.5 earths to sustain the amount of resources we use each year (WWF, 2014). As the growth of the human population shows no sign of slowing down, with predictions there will be a further 2.4 billion people on the planet by 2050 (WWF, 2014), the pressures we exert on the planet will only increase. This overuse of resources is not only making it difficult to support our needs, but is also leaving little space and resources left for all the other species around the globe to thrive, and more importantly, survive. This has led to a decline in biodiversity at a much faster than would be seen under natural circumstances.
According to the Living Planet Index (LPI); which measures the trends in 10,380 populations of 3,038 species of fish, mammals, amphibians, reptiles and birds; biodiversity has been decreasing rapidly, with records showing a 52% reduction in the size of these populations from 1970-2010
