Scientists believe that without plants, people would not be able to live. While46 provide living things on Earth with oxygen, they also help balance the different gases in the air, especially carbon dioxide. Humans and animals take in air and let out carbon dioxide.Nature produces this gas ...

Every tonne of carbon emitted today will contribute to a greater concentration or “stocks” of carbon dioxide that remain in the atmosphere for decades – meaning a stronger heating effect for longer. That’s why many climate experts talk about a “time value of carbon” as GHGs reduc...
Last year, we started to think how we could balance out our environmental impact. Many Supercellians had already compensated for their flights, for example, by using carbon off-set services. What these services do is nurture things that suck carbon dioxide out from the atmosphere, for example ...
But that doesn’t make Mars habitable on any large scale. To make Mars truly habitable, we would need to create an atmosphere that is comparable to that on Earth. That means keep the existing carbon dioxide, which is at an abundance close to that on Earth (considering that Mars’ total ...
One of the big reasons why climate change is happening is that people are letting too much carbon dioxide(二氧化碳)get into the air. Well, trees can take in carbon dioxide out of the air, which can help slow down climate change.Trees are also great at taking in water. This is really ...
Plants take oxygen carbon energy from the sun and use it to turn water and CO2 into 44.dioxide Through photosynthesis, plants not only create their own food, but also release(释放) oxygen into air. Photosynthesis is a complex(复杂的) process. First, the green colouring in leaves(chlorophyll...
Climate change affects many parts of life. It affects how we make food. It can also cause floods. Scientists say that countries must take action. But what can you do to pitch in? Here are 10 things you can do ...
Just like applying pressure to solid carbon dioxide can turn it into a more exotic phase (the supercritical phase) it has been theorized that applying a great deal of pressure to solid hydrogen could turn it into a metallic phase, though no one has succeeded in synthesizing this metallic phase...
