Question

Name three human activities that are changing the natural world. Why do these activities make it important to understand evolution?

Answer 1

Habitat degradation and fragmentation, introduction of exotic species and over harvesting.

These activities disrupt the natural function of a variety of species.

Humans must understand evolution to assess the effect these activities can have on various species and the environment

Answer 2

The three human activities that are changing the natural world are:
1. Deforestation. Cutting of trees results to the endangered habitats of animals and the soil compaction is becoming less and less.
2. Hunting. Killing animals mercilessly and selling them off reduces their numbers and increase the fear of humans
3. Genetic engineering. Modifying the cell structure of a plant or animal increases possible risk of cancer, toxicity in the soil and others.
