2. Environmental Science is the study of the myriad interactions between humans and the world around them, living and non-living.  As Earth’s human population continues to grow, as technology advances and human needs and wants increase, our impacts on the world become more widespread and severe, despite improvement in some areas.  Environmental impacts, in turn, affect human health and well being.  A few of the major challenges that are topics for environmental science include: Global Climate Change (global warming, its causes and all of its consequences) World population Air pollution and acid deposition (rain) Water pollution The loss of fisheries The spread of infectious diseases

3. There are many things that each and everyone of us can to do help protect our environment and reduce the impact that our life styles and way of living has on the environment. If we each do our bit for the environment, no matter how small, we can create a positive reversal on negative impact. By becoming more environmentally aware and through reducing each of our own carbon footprints, we can minimize the detrimental effect we have on our world.

4. The vast muddy expanses of the abyssal plains occupy about 60 percent of the Earth's surface and are important in global carbon cycling. Based on long-term studies of two such areas, a new paper in the Proceedings of the National Academy of Sciences (PNAS) shows that animal communities on the abyssal seafloor are affected in a variety of ways by climate change
