Human caused reductions of biodiversity, include pollution, invasive species, and overexploitation.
Andrew [12]

Answer:

True

Explanation:

Development, together with globalization, drove severe changes at a global level. The natural and original environments suffered from these effects and still are.

Human beings have constantly been altering the natural ecosystems and causing irreparable damages to nature. For many decades, development involved society and technology advance over new areas unpopulated by humans.

<u>Some</u> of the principal human activities responsible for biodiversity loss are

  • the uncontrolled use of unrenewable resources,
  • overexploitation of renewable resources;
  • land destruction for the mining industry, farming and cattle industry, buildings, and other infrastructures;
  • the unplanned advance of cities, and opening of new roads to connect those cities.  

All of them involving

  • deforestation and fragmentation of natural landscapes;
  • water, air, and soil pollution,
  • species loss, and reduction of biodiversity.

With globalization, transport around the world became normal. And when traveling around the world, new species are intentionally or unintentionally transported too. When these species, of animal or vegetable origin, get established in a new area, they overgrow to the point of turning invasive.

Invasive species are uncontrollable and cause severe damage in native endemic species by competing for resources. The whole ecosystem structure changes.

But there are some background glitches in the system that are the principal responsible for all the mentioned activities. Some important aspects are lacking

  • The respect for nature,
  • People´s education at different levels to care and protect wildlife,
  • Interest in keeping ancestral knowledge,
  • Planning and previous environmental impact studies,
  • Policies to control human activities,
  • Caring involved government.

If, as a society, we lack these aspects, the possibilities of changing our impact on nature are far away.

Choose all that apply.
Elodia [21]

The correct answers are options:

1. Amphibians evolved before land reptiles.

4. Elephants appear in the fossil record after dinosaurs became extinct.

The relative dating is a technique of dating with respect to any past event. In this case, two events are discussed to be occurred in a sequence related to one-another. In the option 1, the amphibians are said to be evolved before reptiles. So, the evolution of the amphibians is relatively dated with the evolution of reptiles. Same in the option 4, the evolution of the elephants is relatively dated with the extinction of the dinosaurs.
