Plastic can take up to 1,000 years to break down, so it builds up in the environment, damaging soil, poisoning groundwater, and choking marine wildlife. Microplastics enter the human body with the potential to cause serious health impacts – and have even been found in the placentas of ...
it is assumed that the concrete is exposed and uncoated. Various particle diameters are considered. Demolition emissions (dotted lines) associated with crushing the concrete down to the respective particle diameters are also included.bSummary table of greenhouse gas reductions relative...
Even so, while cardboard definitely counts as green packaging, it has environmental drawbacks. When it’s dumped into landfill sites, its biodegradation emits methane gas, creating a substantial carbon footprint. Moreover, it’s made of tree fibres, so it adds to the ri...

Anther human activity leading to earthquakes is hydraulic fracturing (水力压裂) for oil and gas. In this process, water, sand, and chemicals are forced to flow underground under high pressure to fracture rocks to let natural resources out. As those resources, such as oil and natural gas, make...
Water is found in all three states on Earth which are gas, liquid, and solid. As gas, water is found as water vapor in the atmosphere. In liquid form water is found in streams, rivers, lakes, ponds, and oceans along with mist in the air and as dew on the surface of the ground....
As the world struggles to limit warming to 1.5 or 2 °C below pre-industrial temperatures, research into solar climate interventions that could temporarily offset some amount of greenhouse gas-driven global warming by reflecting more sunlight back out to space has gained prominence. These solar clim...
Sally Morrison, CMO of Lightbox, elucidates further. 'The difference is that while a natural diamond is made over billions of years and comes from deep in the ground, a lab-grown diamond is literally made in a factory over a period of about two weeks. It's something less precious, maybe...
Here are the used Toyota RAV4 years to avoid: none. As mentioned above, a well-maintained Toyota of any kind will last you. If you are looking for something that promotes a little more ruggedness and simplicity, an older generation might be something to shop for. If you are looking for...
