Answer:
Poor recycling habits - recycling is a very important activity for sustainable development, because it reduces the amount of goods that have to be produced, and it contributes to the dematerialization of the economy. If a family does not recycle properly, or does not recycle at all, that family is hindering sustainable development.
Showers that are too long - very long showers do not help sustainable development because they are a waste of water. If the shower is warm or hot, the problem is worse because there is also excessive consumption of electricity or gas.
Too much use of heating or air conditioning - air conditioning and heating should only be used when absolutely necessary (when it is too hot or too cold). If these two systems are used without care, a huge amount of energy will be used, which will not only be reflected in the utility bill, but also in the Earth's resources.
Snow avalanches can be compared to landslides. Loose-powder avalanches move like a flow and slab avalanches move like a slide.
<h3>
What is Avalanches?</h3>
Avalanches can start spontaneously, as a result of causes like increasing precipitation or decreasing snowpack, or by outside forces like people, animals, and earthquakes. Large avalanches can catch and move ice, rocks, and trees. They are mostly made of rushing snow and air.
The two main types of avalanches are slab avalanches, which are built of tightly packed snow and are caused by the collapse of a weak snow layer beneath them, and loose snow avalanches, which are made of looser snow. Avalanches typically accelerate quickly after being triggered and increase in bulk and volume as more snow is gathered. A powder snow avalanche could emerge if an avalanche moves quickly enough to mix part of the snow with the air.
