For billions of years, the sun has illuminated the earth, giving life to flora and fauna of all kinds. Scientists believe that this star is 4.6 billion years old, and has only gotten to around half of its lifecycle. This star is right at the center of the solar system, and one of the most important spheres of human existence, both literally and figuratively.
The start of the planting season is always such an exciting time especially if it was your first ever garden. It’s an opportunity to meet up with friends to swap ideas, go plant shopping for new tools, seeds and seedlings, and it generally means the warmer weather is on its way. You also get to take part in the daily excitement of plucking ripe fruit and vegetables – an inevitable smorgasbord for your family to enjoy, fresh from the garden. It’s always such a feeling of accomplishment.
Recycling is the process of turning what we consider 'rubbish' into new, reusable products. Now, more than ever, we need to be recycling our household waste to save materials and lower greenhouse gas emissions. Can you imagine the impact we'd make on the environment if every single one of us recycled all our waste?
Many of us don't think twice about throwing used remote, car or toy batteries into the trash can. It's now out of sight and out of mind, but did you know that batteries being thrown away like trash can contaminate soil and pollute waterways?
As the finite resource of fossil fuel which includes coal and oil becomes limited in satisfying the present energy demand, alternative energy sources are now sprouting promising new technologies that can reduce our dependency on fossil fuels. One of this so called alternative energy sources is green energy.
With a steady increase in price plus the use of insecticides and pesticides during cultivation, many have thought of growing their own vegetable. But for beginners, making your own vegetable garden is not as easy as counting one two three since there are methods and techniques that you need to follow for you to have a good vegetable produce.
This energy can be simply described as the heat that originates from the Earth unlike how solar energy is from the sun. It is a fact that that almost everywhere on the Earth’s surface, the thermal temperature is constant. This heat is what is pumped to either cool or heat buildings. After a cycle of usage, this heat is again stored in the Earth.
Trying to harness the sun’s energy for useful purposes has sparked the interest of many scientists for thousands of years and it still continues in today's times. Our star, "the sun", has been used a source of energy, not just by humans, but also by the many other life forms on earth. Plants use it to grow while many animals have found the sun's light to be their ultimate guide during the day. We, humans, have also utilized sun's many benefits even as cavemen. The more technological times demand more energy and we now have methods to convert solar energy to electrical energy.
