Renewable Resources
Renewable resources are resources that are replenished by the environment over relatively short periods of time. This type of resource is much more desirable to use because often a resource renews so fast that it will have regenerated by the time you've used it up.
Think of this like the ice cube maker in your refrigerator. As you take some ice out, more ice gets made. If you take a lot of ice out, it takes a little more time to refill the bin but not a very long time at all. Even if you completely emptied the entire ice cube bin, it would probably only take a few hours to 'renew' and refill that ice bin for you. Renewable resources in the natural environment work the same way.
Solar energy is one such resource because the sun shines all the time. Imagine trying to harness all of the sun's energy before it ran out! Wind energy is another renewable resource. You can't stop the wind from blowing any more than you can stop the sun from shining, which makes it easy to 'renew.'
Any plants that are grown for use in food and manufactured products are also renewable resources. Trees used for timber, cotton used for clothes, and food crops, such as corn and wheat, can all be replanted and regrown after the harvest is collected.
Geothermal energy is a renewable resource that provides heat from the earth - 'geo' means 'earth' and 'thermal' means 'heat.' You know all of those volcanoes on Earth that spew hot lava when they erupt? That lava has got to come from somewhere, right? It's actually sitting underneath the earth's surface as incredibly hot rock and magma.
We find the most heat in places like plate boundaries because these are like large cracks under Earth's surface where the heat can escape as well as places on Earth where the crust is relatively thin. Old Faithful and other natural springs and geysers are the result of geothermal energy, and that water can be hotter than 430°F!
Biofuels are renewable resources that are fuels made from living organisms - literally biological fuels. Ethanol is a biofuel because it's derived from corn. Biodiesel is vehicle fuel made from vegetable oil, and I bet you didn't know that people can actually run their cars on used oil from restaurants! Firewood, animal dung and peat burned for heat and cooking purposes are also biofuels because they come from living (or once-living) organisms.
A non-renewable resource (also called a finite resource) is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames. An example is carbon-based, organically-derived fuel. The original organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas. Earth minerals and metal ores, fossil fuels (coal, petroleum, natural gas) and groundwater in certain aquifers are all non-renewable resources.
In contrast, resources such as timber (when harvested sustainably) and wind (used to power energy conversion systems) are considered renewable resources, largely because their localized replenishment can occur within timeframes meaningful to humans.

“Water insecurity, further exacerbated by climate change, is arguably the most impactful factor on India’s food security. India’s total water availability per capita is expected to decline to 1,240 cubic metres per person per year by 2030, perilously close to the 1,000 cubic metre benchmark set by the World Bank as ‘water scarce’.”
In the list of 122 countries rated on quality of portable water, India ranks a lowly 120.Although India has 4% of the world’s water, studies show average availability is shrinking steadily. It is estimated that by 2020, India will become a water-stressed nation. Nearly 50% of villages still don’t have any source of protected drinking water.
Therefore, there is an urgent need to look for alternative sources of portable water in places where water quality has deteriorated sharply. Community based water quality monitoring guidelines should be encouraged. People should be encouraged to look at traditional methods of protecting water sources. Also in places where groundwater has arsenic or fluoride, surface water should be considered as an alternative.
WATER IS VERY ESSENTIAL FOR LIFE.

Guyz! Check out my recent self-made movie on food and how it affects our ecology and our environment. This video also has the advantages of junk food over healthy eating habits. Make sure you watch it once.
