Global warming is accelerating faster than the ability for natural repair, and environmental stresses are damaging ecosystems, all affecting physical and biological systems on Earth. A new Nasa-led study shows that human activity has caused climate changes resulting in permafrost thawing, acid rain, and lower productivity in lakes as well as increased emissions of greenhouse gases, including CO₂, N₂0, CH₄, CF_3, and CFC. Marine plants play a vital role in maintaining the balance of marine environments, while serving as a source of food for...
