1. Renewable energy and fuel source production
2. Industry and raw material compounds like timber, fabric, latex, biofuels, and pesticides
3. Many medicines (like aspirin or morphine) originate from living organisms
4. Wildlife and natural scenery is a source of income for many countries through tourism
5. Microorganisms are the source of many useful products, including antibiotics

Ecotourism is a form of tourism that encourages visitors to experience natural environments while promoting conservation and sustainable development.

A keystone species is an organism with a major role in maintaining the structure of an ecological community and that has a disproportionately large effect on its environment.

Decomposers like bacteria and fungi play a crucial role in breaking down organic waste material and recycling elements, such as carbon, nitrogen, sulfur, and phosphorus.

This makes these substances available to other organisms in the ecosystem.

1. Biodiversity enriches our environment and provides inspiration for musicians, artists, photographers, poets, and writers
2. Natural environments may help people recover from stress and injury

1. Food webs rely on multiple species, so declines in certain species can disrupt food chains
2. Losing keystone species destabilises ecosystems
3. Nutrient cycles depend on decomposers recycling matter

1. Diverse ecosystems provide environmental services
2. Forests and peat bogs absorb carbon dioxide
3. Organic waste material is broken down by microorganisms

We have no right to drive other organisms to extinction as we share our planet with them.

Instead, humans should protect and value these organisms.
