Ways to Learn!

Students could can take a field trip and notice the real side over their activities (I would better say 'connect their learning to the lear world with hands-on activities). It is also something very interesting, and where students can make their best. Every activity, which takes place outside of their school,(no commas needed, this information is relevant - please, read more on defining relative clauses) will be an excuse  a chance\opportunity to learn in a different way. These This/Such type of tasks, not only will be  will not only be an activity to learn about wildlife but it will also to motivate them students to take part as volunteers (because 'them' or 'students'). When they take this field trip, they will notice the majority of people who look after the environment and wildlife (Or you can rewrite it this way: Yaking such a trip will help students see how people are looking after/taking care of the environment and wildlife)

To sum up, if we want to ensure a right future for the environment (you can say: if we care about the future of the environment\ if we want the future of the environment to be bright \ if we want to save the environment for future generations, etc.), we need to involve young people in this task. We just need to think come up with a different activity to ensure that they want to participate. (There are things which are always a good way). Working with other schools and doing participating in / engaging students into outside-school activities (or extracurriaular activities) will always be always (always between the auxiliary verb 'will' and the verb 'be' is better) fine  a nice option \ will go a long way (idiom), etc.)

Hope this helps! And nice thoughts, Antonio! We do need to care about our Mother Earth!
