Global warming is one of the “hottest” issues nowadays. The current climate change is the worst yet to happen. Global warming is an overall increase in world temperature which is attributed to the increasing number of greenhouse gases trapped in the atmosphere. Searching an alternative energy source is considered a way of reducing the toxic emissions.

Greenhouse gases can be produced both by natural and industrial processes. The most abundant greenhouse gases on earth’s atmosphere are water vapour, carbon dioxide, methane, nitrous oxide, ozone and CFCs.

There are several sources of greenhouse gases. Burning of fossil fuels and deforestation lead to higher concentration of carbon dioxide in our atmosphere. Without the trees and plants to take in the carbon dioxide emitted by burning fossil fuels, natural gas and petroleum products, all of the CO2 emitted stays in the atmosphere.

The process, which increases the temperature of air in the lower stage of atmosphere by the reason of green house effects and pollution, is called global warming.

is a serious condition that affects our planet.  It is important to be aware of the human causes of global warming in order to prevent additional global warming from occurring.  While humans supply a lot to there are also natural ways in which occurs.  For these types of situations there is little that can be done to stop the global warming which may occur.

When choosing a new greenhouse for your garden there are several things to bear in mind if you are going to get the most from your choice. A wrong decision can prove costly in the long run so be sure you know exactly what you need before you buy. Here are some of the most important things to consider:

What Do You Need Your Greenhouse For?

If you are looking to grow flowers or vegetables all year round then a tightly sealed, insulated greenhouse with good light transmition, ventilation and heating will be most desirable. However, if your greenhouse will only be used for germinating seedlings or wintering less hardy plants through light winters then a simple plastic frame with a polythene covering will no doubt suffice.
