Human societies depend on healthy ecosystems (生态系统). People use their products in the shape of fish, meat, crops and fibers such as cotton and silk. Medicines may be directly harvested from the natural world or inspired by molecules (分子) and elements found within it. Through light react...
Most at risk to storm surges and sea-level rise, which threaten human communities as well as natural ecosystems like coastal marshes and barrier islands across the coast. The Gulf Coast sits on a sandy foundation, with only low elevation freshwater wetlands standing between its beaches and bays....
“Fish are crucial for coral reefs to function as healthy ecosystems,” Tim Gordon, lead author of the study and a doctoral student at the University of Exeter, said in the statement. “Boosting fish populations in this way could help to kick-start natural recovery processes, counteracting the...

Ecosystem Disruption: Many ecosystems could collapse or undergo severe stress due to the sudden change in climate and the loss of plant life. This would affect the entire food chain, from plants to herbivores to predators. Economic and Social Collapse: The impact on agriculture and infrastructure,...

Elephants’ important role in maintaining biodiversity and healthy ecosystems has earned them various names including ecosystem engineers and forest gardeners. However, African forest elephants — a species living in the rainforests of central Africa — are increasingly recognized by another name: “climate...

The same applies for our oceans. We need to protect the marine ecosystems fisheries depend on. Fish stocks must be kept at sustainable levels, while aquaculture – whichcurrently provides more than 40%of all fish consumed – must incorporate "circular production". This includes strategies such as...
题目Rivers are earthly arteries(要道) for the nutrients, deposits and freshwater that sustain healthy, diverse ecosystems. Their influence extends in multiple dimensions-not only along their length but below-ground to aquifers(蓄水层) and periodically into nearby floodplains. They also ...
