Answer:
Industrial activity increases the emission of greenhouse gases in the atmosphere, especially carbon dioxide (CO2), and it negatively affects climate by increasing global warming.
Two actions to face the global warming:
1- To substitute the use of fossil fuels by alternative clean energy sources such as, for example, hydroelectric, geothermal, solar and wind energy resources.
2- The government's policies decided to develop electric cars and to stimulate healthy habits such as walking instead of the use of conventional fossil-fueled transport modes.
Significant figures are all the digits excluding leading zeros for small decimals and zeros at the end of an integer.
45.030 has 5 significant figures because the zero at the end is after the decimal point. This means that the number was measured with 3 decimal places of precision. If the last zero was not significant, the number would be written 45.03.
On the other hand, 45030 only has 4 significant figures. Hope this helps!
