Clean Air, Green Earth: An Arsenal of Tech to Protect Our Planet #infographic
Fossil fuels currently drive around 90% of energy production levels. Latest figures suggest that our most plentiful resource, coal, has a maximum lifespan of 250 years, with oil and natural gas falling much shorter. This infographic outlines how a dependence on fossil fuels is putting the long term future of our planet in jeopardy.
A lot of people think scientists will find another planet but it takes a lot of time for scientist to search for things in space and sometimes what they are looking at may not even exist anymore save our planet it's the only one
If there's intelligent life within 100 light years of our planet, it's likely they've already gotten an earful (or antennae-ful, or whatever analogous organ-ful) of our radio and TV shows, which have been leaking into space since we first started broadcasting them. Scientists have also sent messages, images and even phonograph records into space in order to show E.T. that humanity isn't just about 'The Lone Ranger' and 'I Love Lucy.'
In case you didn’t know, the universe is a terribly hostile place for most lifeforms. At least, it is if you don’t have proper protection. Take our own star, for example. The Sun gives life to everything on Earth, but it is also a violent inferno that shoots off high energy particles that could seriously disrupt Earth’s natural systems. Fortunately, for us, our planet has protection. Ultimately, the Earth is encased in a magnetic field, which is generated by the rotating, liquid iron core at…
15/04 - Dia da Conservação do Solo Erosão, compactação e aumento da salinidade do solo são os maiores problemas relacionados ao manejo inadequado. Terão relação direta com escassez de alimentos em futuro não distante, profundo desequilíbrio do sistema produtivo, se praticas corretas não forem adotadas. Manejo inadequado reduz significativamente potencial de produção. Renovação, aprimoramento das técnicas produtivas e redução de desperdícios são fundamentais.
