The definition of bioplastics is still up for debate. The phrase is frequently used to refer to a wide range of diverse goods that may be biobased, biodegradable, or both. This could imply that polymers made from oil can be branded as "bioplastics" even if they have no biological components at all. [5]
Bioplastic panels, made from blends of natural fibers and biopolymers, provide an eco-friendly option for wall cladding and partitioning. These materials are lightweight, durable, and can be designed to mimic traditional materials like wood or stone. Formwork Bioplastics are increasingly used in formwork for concrete casting.
According to the OECD, plastic contributed greenhouse gases in the equivalent of 1.8 billion tons of carbon dioxide (CO 2) to the atmosphere in 2019, 3.4% of global emissions. [123] They say that by 2060, plastic could emit 4.3 billion tons of greenhouse gas emissions a year. The effect of plastics on global warming is mixed.
Global warming is not caused by the hole in the ozone layer. Ozone depletion is a separate problem caused by chlorofluorocarbons (CFCs) [231] which have been released into the atmosphere. [232] However, CFCs are strong greenhouse gases. [233] [234] Further, the hole in the ozone layer is shrinking and in 2019 was the smallest it had been since ...
The controversies are, by now, mostly political rather than scientific: there is a scientific consensus that global warming is happening and is caused by human activity. [2] Public debates that also reflect scientific debate include estimates of how responsive the climate system might be to any given level of greenhouse gases (climate sensitivity).

As reported by the Intergovernmental Panel on Climate Change (IPCC), most of the observed global warming since the mid-20th century is very likely due to human-produced emission of greenhouse gases and this warming will continue unabated if present anthropogenic emissions continue or, worse, expand without control.
Berberine, a plant compound traditionally used in herbal medicine, is today commonly stocked on the shelves of health food stores and pharmacies as a supplement. Beyond weight loss, berberine also ...
