Why are nonhuman animals victims of harm?

...carbon dioxide (CO2). CO2 is a key greenhouse gas (GHG) responsible for anthropogenic climate change (that is, caused by human activity) (Garnett, 2013). By contrast, a recent research review concluded that plant-based diets could sustain the global human population from half the agricultural land currently in use (Chai et al., 2019). In terms of water, ‘livestock’...

...carbon dioxide, nutrients and waste materials' [p. 36] can transfer between mother and offspring. In marsupials, this contact is loose and seldom any more than a very rudimentary 'placenta of sorts'. But in some marsupials, the contact between the two sets of tissues becomes more elaborate; in the koala, for example, the structure is considered by most experts to be a...

...carbon dioxide gas, it is also possible for scientists to measure temperatures within the atmosphere, not just at the cloud tops. This is done by a careful calculation of the amount of IR radiation expected to be seen at a whole series of frequencies for a particular distribution of temperatures all the way along the line of sight. That distribution of temperatures is...

...carbonated drink. Obviously, there’s water. There may be some additional flavours. There are, on some drinks, some stabiliser and preservative systems. On other drinks, it’s entirely aseptic, so the main ingredient there is no bugs in the manufacturing environment. So primary ingredients, that’s the liquids and the syrups. The primary packaging will be your preforms...

...carbon dioxide, some inorganic materials from the soil, and light energy. Similarly a human baby grows into an adult by digesting and metabolising food and drink. The parents in each case pass to their progeny, or offspring, the information and specification for building cells from materials around them. This information lies in the genetic material, or DNA, which is...
