Earth’s resources series - Agriculture

Earth contains many useful and essential natural resources, which have been used heavily by humans in recent centuries.
These resources include water and food, fuel and building materials, and the means to make more complex things like metals and plastics. Many resources have a limited supply, and using them has an impact on the environment.

Growing food plants and looking after animals that will be eaten is called agriculture. Today, the global population of around seven billion people largely relies on a few cereal crops to provide its essential foods. These crops include corn, wheat, rice, potatoes, cassava, soybeans, and sweet potatoes. Protein from livestock such as fish, cattle, pigs, and poultry makes up less than 20 percent of total global food. [WATCH THE VIDEO]

Earth’s resources series - Energy

Earth contains many useful and essential natural resources, which have been used heavily by humans in recent centuries.
These resources include water and food, fuel and building materials, and the means to make more complex things like metals and plastics. Many resources have a limited supply, and using them has an impact on the environment.

Human life requires energy in the form of light, heat, and food. Earth’s energy comes from a variety of sources but mostly from the heat of the Sun and the Earth’s hot interior. This is a lot of heat, but capturing, storing, and transporting enough of this energy to meet all our needs is difficult and requires complicated and expensive technology. [WATCH THE VIDEO]

Earth’s resources - Rocks and minerals
Earth contains many useful and essential natural resources, which have been used heavily by humans in recent centuries.
These resources include water and food, fuel and building materials, and the means to make more complex things like metals and plastics. Many resources have a limited supply, and using them has an impact on the environment.

Over the more than four billion years of Earth’s development, thousands of different minerals have formed and combined into hundreds of rock types.
Humans have found many uses for these rocks and minerals, from building materials to the manufacture of metals.
However, some of the most useful and valuable minerals are rare. Mining and quarrying them is often dangerous and dirty. [WATCH THE VIDEO]
