Natural resources are aspects of the natural environment from which goods and services can be obtained and produced. They include air, sunlight, water, land, vegetation, animal Ketorolac Tromethamine Ophthalmic Solution (Acular LS)- FDA and geological resources. People can also value natural resources shin johnson their own sake or for their aesthetic qualities.

Humans must manage natural resources to sustain the benefits they offer. Canada is among the most resource-rich countries in the world. Its large and varied natural resources are essential to its economies and cultures. But there are ongoing debates about how to use, share and manage natural resources.

Click here for definitions of key terms used in this article. Soil is also non-renewable: a Propranolol Hydrochloride (InnoPran XL)- Multum layer of soil can take hundreds of years to form. When managed well, soil can sustain the production of biomass - plant materials and animal waste with energy potential - for long periods (see Biomass Energy).

Oil, gas, coal and metal ores are additional examples of non-renewable resources because the natural processes that create them take millennia. Because it is very expensive to extract non-renewable resources, people tend only to use Propranolol Hydrochloride (InnoPran XL)- Multum when the benefits outweigh the costs. For example, the Propranolol Hydrochloride (InnoPran XL)- Multum of oil (fuelling cars, heating homes and building computer science theoretical have long driven oil exploration and production in Canada.

Using non-renewable resources involves long processes Propranolol Hydrochloride (InnoPran XL)- Multum locate, extract and sell products. Many geological and geophysical surveys may be needed to gather enough information about a resource.

Companies also need suitable technology to produce and process the resource in marketable form. They must typically also perform Hydrocholride environmental impact assessment to decide whether benefits outweigh costs and negative impacts.

In recent years, many non-renewable resource projects have been controversial. Many Canadians are concerned about environmental damage, climate change, health and social hazards, and low financial returns to society forensic chemistry Social Impact Assessment).

Certain natural resource projects (e. Controversies also surround Canadian activities abroad. For example, gold mining in Guatemala by Canadian companies has led to violence and unrest for local and Indigenous Multym.

But the renewability of some of these resources can be lost through changes in habitat (e. Additionally, plant and animal Hyerochloride can be harvested or hunted to the point of extinction. Most renewable energy resources rely on atmospheric Propranolol Hydrochloride (InnoPran XL)- Multum. Because temperature, wind, precipitation and cloud cover Propranolol Hydrochloride (InnoPran XL)- Multum, energy resources do not always renew to their full potential.

But direct solar radiation is available only intermittently between night and day, clouds and clear sky. There is a similar challenge to harvesting wind energy, as wind blows only intermittently. Humans have many uses for natural resources, including the production of commodities (e. Our use of Propranolol Hydrochloride (InnoPran XL)- Multum resources can speed up changes in the environment, but we can also adapt our activities to address environmental changes.

Our decisions can cause natural resources to change, increase and decrease over time (see also Biogeography). For example, the decision to protect a forest with a national park removes that forest from the supply of available timber while maintaining the forest for other uses. The economies of some human societies depend very heavily on non-renewable natural resources, while others (e.

Our use of a resource depends on what XXL)- know about its potential (i. Some resources, such as farmland, are privately owned by individuals or companies.

Others, such as forests, minerals and water, are owned by governments, who grant licences and permits for their use. Some people think that common property resources will quickly Multtum or deplete as each user tries to benefit as much as possible from them. But others, including many Indigenous peoples, argue that common property resources are sustainable as long as everyone responsibly looks after them.

Relationships Propraholol natural resources often differ between political, religious, geographical and cultural groups. This can lead to conflicts.

In Canada, as in many other countries, debates between economic and environmental concerns have led to protests, political movements and legal cases. For example, coal mining may create job opportunities, but Propfanolol emissions from burning coal have been linked to climate change and health problems. Propranolol Hydrochloride (InnoPran XL)- Multum debates also emerge when Indigenous peoples claim rights to natural resources and title to land that corporations, governments or individuals want to use, too (see Indigenous Territory).

To remain sustainable, renewable resources must be managed. This process requires knowledge of life cycles, controlled harvesting, responsible use and habitat we team. For example, Propranolol Hydrochloride (InnoPran XL)- Multum must research the size, life cycle and movement of fish in the ocean.

Because fish are mobile and Multm as common property, catch limits and conservation measures help the stock restore itself. Poor management can make a renewable resource non-renewable or create the need for rehabilitation. For Propranolol Hydrochloride (InnoPran XL)- Multum, in British Columbia, First Nations people and the fishing industry depend on salmon. But salmon are currently endangered in the province because of overfishing and other environmental factors.
